OUTPUT DATA FORMAT
The MT9M034 image data is read out in a progressive
scan. Valid image data is surrounded by horizontal and
vertical blanking (see Figure 7). The amount of horizontal
row time (in clocks) is programmable through R0x300C.
The amount of vertical frame time (in rows) is
programmable through R0x300A. Line_Valid (LV) is HIGH
during the shaded region of Figure 7. Optional Embedded
Register setup information and Histogram statistic
information are available in first 2 and last row of image
data.

Readout Sequence
Typically, the readout window is set to a region including
only active pixels. The user has the option of reading out
dark regions of the array, but if this is done, consideration
must be given to how the sensor reads the dark regions for
its own purposes.
